BofA, Mizuho have designs on street

of America is bullish on New York — and on Sixth Avenue.

Just eight months after Brookfield Properties and California’s Swig Co. bought the leasehold on 1100 Sixth Ave., Bank of America, led by Chief Executive Brian

Moynihan, plans to expand from its One Bryant Park headquarters into the entire 386,000-square-footer across Sixth Avenue that’s been home to premium cable channel HBO since 1981, The Post has learned.

Corporate and real estate sources confirmed the bank’s hop across the avenue. HBO is to move along with parent company Time Warner to Related Cos.’ new 30 Hudson Yards in 2019. HBO’s relocation isn’t expected to be affected by Time Warner’s proposed $85 million sale to AT&T, which the Justice Department on Monday moved to block.

Brookfield is expected to soon announce a top-to-bottom redesign of 1100 Sixth. The publicly traded giant knows from redesign — its 5 Manhattan Yards, 450 W. 33rd St., is unrecognizable from its ugly concrete-faced old self after a $350 million recladding in crystalline glass.

Brookfield and Swig — which is not New York’s Swig Equities — bought a long-term leasehold on 1100 Sixth from William H. Nickerson’s Eugene A. Hoffman Management Inc.

As we first reported Monday at nypost.com, global management consulting giant McKinsey & Co. is moving its headquarters from 55 E. 52nd St. to Three World Trade Center.

The deal — kept so under wraps that not even word of negotiations seeped out — is a Thanksgiving present for developer Larry Silverstein. It’s also a gift to the thriving downtown office scene, which boasts a healthy mix of media, creative and traditional financial firms.

But it’s another loss for East Midtown, where the effects of recent rezoning to allow large new modern buildings to rise might not be felt for years.

Although fine points of the lease have yet to be worked out, McKinsey executives were told of the planned move in a memo last week. Many employees were treated to a walk-through of their new home.

Sources said that McKinsey will take about 200,000 square feet on floors 60 to 64 of 80-story Three World Trade Center, including a 5,000-square-foot, south-facing outdoor terrace on the 60th floor.

Once the 15-year lease is signed, as is expected, McKinsey will join GroupM at the

Richard Rogers- designed tower.

The building is to open in May. The lease would raise office occupancy to 900,000 square feet in the 2.5-millionsquare-foot tower.

Terms were not known, but office asking rents at 3WTC have been reported in the $80s per square foot.

McKinsey has some 14,000 “consultants” in 120 cities around the world. The Manhattan office, which it will leave behind, is the firm’s largest, with more than 900 executives.

Silverstein declined to comment, and reps for McKinsey couldn’t immediately be reached.

In another mega-deal on Sixth Avenue, Mizuho Americas has signed for 270,000 more square feet at Rockefeller Group’s 1271 Sixth Ave., the former Time-Life Building, at West 50th Street.

That’s on top of a 141,000square-foot lease Mizuho signed there in June. The new deal brings the bank’s total commitment in the 2.1-million-square-foot tower to 411,000 square feet.

Mizuho will be the redeveloped tower’s largest tenant, topping MLB, which originally signed for 400,000 square feet but recently scaled back to 325,000 square feet, as The Real Deal reported.

Although the subsidiary of Japan’s Mizuho Financial Group was expected to add more space at 1271 Sixth after it signed the June lease, the size of the new deal came as a surprise. Earlier reports speculated Mizuho was looking at not more than an additional 200,000 square feet.

The Rockefeller Group is in the midst of a $600 million redevelopment of 1271 Sixth designed by architecture firm Pei Cobb Freed — including an entirely new curtain wall.

Mizuho was repped in negotiations by the Savills Studley team of Mitchell Steir, Matthew Barlow, Steve Berliner and David Goldstein. Rockefeller was repped by a CBRE team led by Mary Ann Tighe, Howard Fiddle and John Maher, along with a Rockefeller Group in-house team led by Ed Guiltinan.
